Counterpulsation requires pulsation: IABP use in patients with heart failure without acute MI.

Limited data exploring the utility of IABPs in shock without acute myocardial infarction exist. Counterpulsation pumps depend on native LV contractile function. Hemodynamic monitoring with a pulmonary artery catheter should help guide management of the cardiogenic shock patient. More studies are required to identify the optimal patient population and hemodynamic parameters best suited for IABP therapy.
